製剤の安定性は、常に、第VIII因子医薬組成物を取り扱う医薬工業にとって問題であった。 The stability of the formulation has always been a problem for the pharmaceutical industry dealing with Factor VIII pharmaceutical compositions.
これらの製剤を安定化するのにアルブミンがしばしば使用されている。しかしながら、その興味ある安定化効果にも拘わらず、アルブミンは高価でありまたプリオンのごとき感染生物を担持している危険性があるという欠点を有する。これらの理由から、医薬工業においては、近年、第VIII因子医薬組成物においてアルブミンを他の安定化剤により置換することが行われれている。 Albumin is often used to stabilize these formulations. However, despite its interesting stabilizing effect, albumin has the disadvantage of being expensive and risking carrying infectious organisms such as prions.

混合物を殺菌ビン中で凍結乾燥しついで密閉した。得られた固体組成物を試験し、第VIII因子活性によって試験した場合、2〜8℃の温度では少なくとも18箇月、30〜32℃の温度では少なくとも6箇月安定であることが示された。サイズ排除HPLC(Size Exclusion HPLC)(SECHPLC)により評価した場合には、高分子量成分の形成、また、SDS PAGEで評価した場合にはフラグメントは認められなかった。 The mixture was lyophilized in a sterile bottle and then sealed. The resulting solid composition was tested and shown to be stable for at least 18 months at a temperature of 2-8 ° C and at least 6 months at a temperature of 30-32 ° C when tested by Factor VIII activity. When evaluated by size exclusion HPLC (SECHPLC), no high molecular weight components were formed, and no fragment was observed when evaluated by SDS PAGE.
得られた凍結乾燥混合物は、例えば、患者に注射する前に、1.0mlの殺菌水で再構成されるであろう。 The resulting lyophilized mixture will be reconstituted, for example, with 1.0 ml of sterile water prior to injection into the patient.

分析方法
色素試験(chromogenic assay)
第VIII因子活性を修正色素試験(Technochrom FVIII:C Reagent Kit,Technoclone)により測定した。第IX因子による活性化第X因子の発生を、反応中に助因子(cofactor)として作用する第VIII因子により刺激した。色素基体(chromogenic substrate)からのp-ニトロアニリンの放出を活性化第X因子によって触媒した。放出されたp-ニトロアニリンの量を405nmで測光法により測定し、この測定により生成されたp-ニトロアニリンの量と第FVIII因子との間に直線的関係が得られた。
Analytical method chromogenic assay
Factor VIII activity was measured by a modified dye test (Technochrom FVIII: C Reagent Kit, Technoclone). Generation of activated factor X by factor IX was stimulated by factor VIII, which acted as a cofactor during the reaction. Release of p-nitroaniline from the chromogenic substrate was catalyzed by activated factor X. The amount of p-nitroaniline released was measured photometrically at 405 nm and a linear relationship was obtained between the amount of p-nitroaniline produced by this measurement and factor FVIII.
SECHPLC
可溶性高分子成分及びフラグメントを、蛍光検出器を備えたかつ0.78 x 30cm 予備充填カラムを有するTohoHass TSK G3000 SWXL(Waters LC Module 1 プラス)を使用して、HPLC上でのゲルろ過により測定した。励起波長 280nm及び発光波長340nm。結果の評価はピーク領域の積分によって行った。
SECHPLC
Soluble polymer components and fragments were measured by gel filtration on HPLC using a TohoHass TSK G3000 SWXL (Waters LC Module 1 plus) equipped with a fluorescence detector and having a 0.78 × 30 cm pre-packed column. Excitation wavelength 280 nm and emission wavelength 340 nm. The result was evaluated by integration of the peak area.
SDE PAGE試験
SDE PAGE(フラットベッド式電気泳動装置(Multiphor II LKB)及び予備キャスト7.5%ゲル(EXCELGEL SDS, Pharmacia)を使用するポリアクリルアミドゲル電気泳動)を使用して、第FVIII分子の破壊生成物を測定した。タンパク質バンドをクーマシーブルー染色により可視化した。
SDE PAGE test
SDE PAGE (polyacrylamide gel electrophoresis using a flatbed electrophoresis device (Multiphor II LKB) and pre-cast 7.5% gel (EXCELGEL SDS, Pharmacia)) was used to measure the disruption products of the FVIII molecule. . The protein band was visualized by Coomassie blue staining.
安定性試験
安定性は、前記した評価を選択された温度(この温度は約+4℃又は;+31℃であり得る)に保持された同一の試料について異なる時期に行うことにより評価し得る。その第VIII因子活性が30%以上降下したとき、組成物はその安定性を失ったと考えられる。
Stability Testing Stability can be assessed by performing the above assessment at different times on the same sample held at a selected temperature (this temperature can be about + 4 ° C .; or + 31 ° C.). A composition is considered to have lost its stability when its factor VIII activity drops by 30% or more.
